New account, same bullshit.

Took the girl I've been seeing for 10 months on a weekend trip to my home town (at this point she's assumed my LTR). Introduced her to my high school buds and had her in the palm of my hand the entire time (she's now dependent on me so it's easy to have her entirely in my frame). Despite being as attractive if not more attractive than me, her family comes from a country that idolizes wasian people. In her mind I epitomize her culture's hierarchy. I'm assuming this is why the honeymoon phase seemed to last so long... and I present myself well.

She met my old basketball teammates with me and everything went well but they reminded me that people used to call me spike because I blocked a kid at the layup line and spiked the ball into his nose... breaking it. Sure it's not the worst nickname to have. In fact, she brought it up later and said it turns her on to hear about me playing competitive sports (I now only lift). However, she called me spike... playfully. I laughed it off but told her that she shouldn't call me that.

Fast forward to 4 weeks later (today), and she's really trying to make it a thing. She'll drop it at the end of a 2 hour facetime or facetime sex. I joked once that she had to be on the team to call me that. She's said she should just call me by my last name then (and occasionally now does this as well). I said she's being straight up disrespectful. I won't allow this to become a thing, but need the nuance to not reveal that she can get to me. No guy should take any disrespect, but this is the one thing she's shrugged off.

Do I shut it down once and for all upon hearing it, keep ignoring her, amuse, or show her what spike really means? haha Other than this she has been a keeper (will not next because she's proven loyalty, has no exes, and is very submissive), but I sense I've allowed her to breed too much comfort. How do I proceed? I'm prepared to next if there are any further signs, but this seems to be just a little rebellion.
